What are the major roles in literature circles? Check out this site to learn more about the individual roles needed to form a literature circle. Includes links to various reading handouts and lessons.

How can you get started with literature circles in your classroom? This site provides information on every aspect of developing your own literature circle instruction.

In this task, a model airplane pilot is practicing flying her airplane in a big loop for an upcoming competition. The task could serve as an introduction to periodic functions and as a lead-in to sinusoidal functions. By visualizing the...

This section explores the Pythagorean Identity and how it applies to right triangles set inside unit circles, in terms of sine, cosine, and tangent functions.

Find the sine and cosine of special angles, which are angles whose trig values we can determine without the use of a calculator. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

The purpose of this task is to apply translations and reflections to the graphs of the functions f(x)=cos x and g(x)=sin x in order to derive some trigonometric identities. There are also rotations 180 degrees about points on the x-axis...

[Free Registration/Login may be required to access all resource tools.] This lesson covers changing a general second-degree equation into the standard form of a parabola, ellipse, circle or hyperbola. Students examine guided notes,...

[Free Registration/Login may be required to access all resource tools.] Find all angles on the unit circle matching exact trig ratios. Resource includes examples, videos, and practice problems.

Students explore trigonometry concepts through this collection of definitions, lessons, examples problem-solving steps and strategies, and practice problems. Topics include solving triangles, trigonometric functions, theorems, and the...

These LearningCheck files are designed to determine if students know the unit circle.

[Free Registration/Login may be required to access all resource tools.] Define the cosine and secant graphs using a unit circle.

In this section we will give a quick review of trig functions. We will cover the basic notation, relationship between the trig functions, the right triangle definition of the trig functions. We will also cover evaluation of trig...

This section explores the graphs of sine and cosine functions. It investigates how these graphs are related to coordinates for different angles in a unit circle.

You know that you can take side lengths and find trig ratios, and you know you can find trig ratios (in your calculator) for angles. What is missing is a way to go from the ratios back to the original angles. And that is what "inverse...

In this activity, students can use geometry to determine the optimal location for a distribution warehouse of a department store chain.

Wikipedia offers great information on simple harmonic motion, including an image, formulas, and hyperlinked terms.

THis resource provides examples and information about Algebraic graphing.

The study of biomimicry and sustainable design promises great benefits in design application. It affords means by which to promote cost-effective, resourceful, non-polluting avenues for new enterprise. These "blueprints" have existed...

2 OF 2 FOR ADDITIONAL TOPICS IN MATH. Students will use the coordinate plane and equations of lines and circles to describe figures; create the equation of a circle given the figure or use the structure of a given equation to determine a...

Chapter from a novel that describes the workings of a charitable society. This chapter, "The Sewing Circle," illustrates some of the various functions that institutions, especially the benevolent and charitable societies, performed in...

Radar (which stands for RAdio Detection And Ranging) transmits microwaves in a focused beam. Some of this microwave energy bounces off of objects and returns to the radar to be measured. The radar sends pulses of energy, rather than a...

This is a site for students and teachers of all grade levels. If you are looking for math tables, general information about math topics, or you would like to ask a question, this is the site to visit.

Concepts in Trigonometry are explained and illustrated here by a member of the math department at Borough of Manhattan Community College.

This site offers numerous activities for middle school and high school students to explore using Geometer's Sketch Pad.
